Enhancement of PUCCH Transmissions - A simplified explanation of the abstract

This abstract first appeared for US patent application 17754546 titled 'Enhancement of PUCCH Transmissions

Simplified Explanation

The abstract describes a patent application for a user equipment (UE) that can transmit physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) transmissions based on received downlink control information (DCI) containing a transmission power control (TPC) configuration.

• The UE determines a subset of multiple closed loop indexes or multiple beams for which the TPC command is configured.
• The multiple closed loop indexes and multiple beams correspond to multiple transmission and reception points (TRPs).
• The UE applies the TPC command to PUCCH or PUSCH transmissions corresponding to the subset of multiple closed loop indexes or beams.

Original Abstract Submitted

A user equipment (UE) is configured to transmit physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) transmissions. The UE receives a downlink control information (DCI) transmission including a transmission power control (TPC) configuration, wherein the TPC configuration includes at least one TPC command, determines a subset of (i) multiple closed loop indexes or (ii) multiple beams for which the TPC command is configured, wherein the multiple closed loop indexes and multiple beams correspond to multiple transmission and reception points (TRPs) and applies the TPC command to one or more physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) transmissions corresponding to the subset of multiple closed loop indexes or beams.
